Cleaning non-glare plexi ?

Just wondering if there is a good safe way to clean the plexi glass before putting it in the frame. I have framed some images with kits I got from Frame Destination. I couldn't be happier with what I have been receiving from them, but when I peel off the protective paper it sometimes leaves lines across the plexi. I want to clean with something but just nervous to scratch it.

Any suggestions?

Thanks

Frame Destination sells an acrylic cleaner and cloths. I have used both. The cleaner also helps reduce static.

I also use the Brillianize that Eva linked too. You can also find it at TAP Plastics, if you have one of those. What ever you do, DO NOT use Windex and paper towels. You can scratch the acrylic.

Thanks for the responses. I will have to check that out. Of course I waited to the last second and I am trying to get this done today. I found some spray polish I use to clean my motorcycle with and used it with some really soft cloths. It actually worked really well. But I will def be ordering something different for future use.

Thanks again to you both
